"Be it known that we,ALF'nED SCBLATTER, professor, residing at 72 Vaczi-t, and LUD- WIG DEUTSCH, engineer, residing at 72 Vaczit', Budapest, Austria-Hungary, subjects of the Emperor of Austria-Hunga haveY invented ',cert'ain new and usef Improvements Relat' to Apparatus for Indicating the Amount o Carbonio Acid Contained in Combusti nfGasesfof which the following is as ecification. Y

he invention has for its object an ap ara acid contained in the combustion-gases of furnaces of all kinds, in whichthe as serving for analysis is introduc dinto t e absorption-chamber mechanically b means of a pistonpump, froni'which =it`1s' likewise expelled by a rigid piston after the measurementhas been effected.

The purpose of the presentinvention is to eiect t e suction and forcing in ofthe gas to be analyzed by means of ri 'd lpistons continuous y operated mechaniclly with so considerable a velocity as tov render it possible to whereby the results always give vthe heating dicating the kind o stoking to be adopted, so that 1tmay be regulated by means of these indications, which are constantly shown and TWO constructional forms of the apparatus are `d iagrammatically illustrated in the laccompanying drawings.

In the apparatus shown in Figure 1 the combustion-gases are sucked by the pistonpum a from the pipe b, the valve c being eld y the gear d (an eccentric or the like) in the open position. After the completion of the suction-stroke of the piston-e the valve c is closed by means ofthe gear d. During the pressure-stroke of the pistone the gases sucked in are forced'through the pipe finto the' absorption-chamber g: The mouth of the pipe f, provided with a valve h, is arranged underneath the surface o f the absorption liquid 'i,(potash or s'oda-lye, milk of lime, 1j or the like,) so that the gases are forced to i ass through the absotion liquid in the i ibrm of small bubbles, w ereby a speedy and i complete absorption is produced.

Upon the cover oi tha-vessel g is mounted f a waste-pipe k, in Whicllrjis arranged a valve i l. This valve l is operated by gear mand is closed durinU the pressure-stroke of the piston e. A- cylinder n-'communicates with the vessel g, and in this cylinder a well-fitting piston o is mounted. A connecting-rod 2 connects this piston With the crank-shaft z. The cranks `oi the pistons e and o are displaced relatively to each other bv one hundred and BUDAPEST, -AUsTRIA- ei hty degrees. The capacities of the two cy nders a, n are alike, so that the volume between the two pistons remains constantly the same during the whole of their operation.

A-vacuum-gage 3 is mounted o nthe vessel g, a valve 5 ,being arranged in the 'connectingpipe t and actuated by the gear 6.

Owing to,the fact that a portion of the gases introduced into the vessel g are absorbed by the liquid i, a reduction of ressure Will exist in the 'vessel 'g at the end) of the pressure-stroke of the piston e, and its amount will lie-indicated by the vacuum-gage 3, for which reason the gear 6 is 4so arran ed that the valve 5 shortly before the comp etion of the vpressure-stroke of the piston eis opened and upon the lower dead-point being reached it is closed.

According as the quantity of carbonio acid contained in the gases is larger, a greater quantity of the same will be absorbed, thus producing so much the greater diminution of pressure, which the vacuum-'gage will indicate.

After the complet-ion ofthe pressure-stroke ofthe piston e its suction-strokebegins, the valves c andl being opened, While the valve h .automatically closes. During -the suctionstroke of the piston e the piston o descends and forces the gases contained in the vessel g out through the pipe and valve Z. The arrangement is such that the vessel g is in the 'inoperative condition completely filled with the .absorption li' uid'. In order that anyv The gases s ICO ing after the a-bsorptioii of the carbonic acid.

To this end the pistono is not connected with i v the piston e or the attainment of t e highest .2 5

plate x of the rod t and is set 4. 'inaining after the absorption "3'9- :.;f descend the lever r is released )y the eccentric w, so that the brake-block either under completion of an absorption, a brake-disk -u the quantity of carbonic acid is effected measuring the quantity of the gases remainthe crank-shaft a, but is lifted by the absorpi tion liquid displaced by the gases, and by the intermediary of the rack s and gear-Wheel r acts upon the index p. According as the quantity of carbonic acid contained in the gases is greater a larger quantity of the saine Will be absorbed by the liquid i, so that the piston o Will be lifted to a proportionately ess height, and vice versa.

In order that the index' p may not participate in the entiredisplacement of the piston 0, but only indicate the volume after the is keyed upon the shaft g ofthe index, the end of a two-armed lever v, formed as a brakeblock, resting upon this disk. The lever v is acted upon by an eccentric disk or cam lu1 in such a manner that the brake-block shortly vbefore the completion of the forcing stroke of position of the piston o is lifted from the rake-disk, so that the rack s falls 'upon the by the latter in oi' the gases reof the carbonio acid. As soon as the piston 0 avainbegins to accordance with the volume the influence of gravity or of aspring y-falls upon the brake-disk u. and holds the index. By means of this arrangement the index indicates the result of the preceding measurement during the entire suction and forcing period.

Asshown, the apparatus are actuated by a crank-shaft maintained in continuous rotation, its velocity amounting to, say, six to ten revolutions per minute.

Having now particularly described and ascertained the nature of our said invention and in what manner the same is to be performed, We declare that what We claim is- 1. In apparatus for indicating the proportion of carbonic acid contained in combustion-gases, a piston-pump of deterininated stroke volume, means for continually driving the pump, an absorption vessel, means f for connectingfthe absorption vessel with the piston-pump and means for expelling the i analyzed gases out of the absorption vessel. f I
